FRED H. IDEUS, OF AUSTIN, TEXAS.

SHO GK ABSORB ER.

Application led May 23,

T0 all @a0/om 'it may concern.'

Bc it known that I, FRED H. IDnUs, a citizen of the United States,residing at Austin, in the county of Travis and State of Texas, have.invented new and useful Improvements in Shock Absorbers, of which thefollowing is a specification.

The object of this invention is to provide a shock absorber for motorcars and other similar uses, the device including an oil cylinder, aplunger therein, and particularly means for mounting the elements withreference to the axle and the frame, so that shocks arising from theusual causes will be taken up and the strain on the springs avoided orgreatly reduced.

A further object is to provide mounting means including a plurality ofbars forming a V-structure, the converging ends being pivotallyconnected and the opposite ends being connected respectively with theaxle and the body or frame, the movement of the bars toward andaway fromeach other being governed by the movement of liuid in the cylinder andthrough ports in the plunger.

With the foregoing and other objects in view, the invention consists inthe novel construction and arrangement of elements described andclaimed, it being understood that modifications may be made within thescope of the claims without departing from the spirit of the invention.

In the drawings, Figure 1 is a view in side elevation, showing themounting of the shock absorber; Figure 2 is a view in elevation andvertical section, showing the oil cylinder and plunger; Figure 3 is asection on line SW3 of Figure 2, showing the manner of connecting theoil cylinder with one of the pivoted bars.

The cylinder 10 has operating therein a plunger 11 having ports 12 ofsuflicient number and size to'permit of the flow of oil from one portionof the cylinder to the other. incident to the relative movement betweenthe plunger and the cylinder. The cylinder is provided with a fillingcap 13 and a stuffing box 14 through which the piston'rod l5 passes.

Bars or arms 17 and 18 are pivotally connected at 19, in V-form, and thebar 17 is to 1923. Serial No. 640,970.

be pivotally connected with the frame of the vehicle. The bar 18 ispivotally connected with bracket 19 secured by U-bolt 20 to axle 21, thedevice operating freely alongside of each spring S, and the bars beingnormally spaced at about the angle shown. The bar 17 is pivotallyconnected with the cylinder 10 in any suitable manner, as by means shownconventionally at 23. The piston rod is pivotally connected by elements24, 24 with the bar 18. Grease cups are shown at 25, at the variouspoints where required.

The cylinder is supplied with oil of suitable grade, and it is obviousthat relative movement between the bars 17 and 18 will be resisted bythe somewhat slow movement of the oil through the ports of the plunger,so that the desired cushioning action will result.

That is claimed is 1. A device of the class described, comprising an oilcylinder, a perforated plunger therein, a plurality of bars, disposed atan angle with each other, means for pivotally connecting the bars attheir converging ends, means for connecting the cylinder with one of thebars, at a point intermediate of the ends of the cylinder, and means forconnecting the plunger with the other' bar, said bars being adapted formounting between the frame and the axle of a vehicle, with the divergingends of the bars connected respectively with the axle and frame.

2. A device of the class described, comprising an oil cylinder, aperforated piston therein, a piston rod connected with the piston, aplurality of bars pivotally connected with each other to form a V-shapeddevice, devices for pivotally connecting the bars respectively with thepiston rod and the cylinder, at points equally distant from theconverging ends, the pivotal connect-ion with the cylinder being at apoint intermedi ate of the ends thereof, one end of the cylinder beingfree and projecting beyond the bar to which it is attached, and saidbars being adapted to have their diverging ends connected respectivelywith the axle and the frame of a vehicle. y

In testimony whereof I aix my signature.
